AW3423DWF fan running constantly
I had been using the AW3423DWF monitor without issue since I first set it up. There was never any audible fan noise from the monitor. I just got a new sit/stand desk and had to tear down everything on my old desk - this included taking the monitor cable out from the back of my RTX 6800 XT graphics card and its power cable from the surge protector. After putting everything back together on the new desk and booted up my PC, the monitor fan was clearly audible. It was never like this. I read some forums and support docs - they say the fan is supposed to rev up/down depending on temp. The fan is not doing that on mine - its running at a constant speed. I can feel the air blowing out from the top of it. I have no idea what happened and why its running like this now. I performed every troubleshooting step I could possibly think of with no luck. Seeking help, please advise.

So Dell support just read me the same article I can read online. But I contacted Best Buy and they said the first rule of IT support - turn it off and on. I had done literally every troubleshooting step I could think of EXCEPT pressing the power button on the monitor to turn it off and back on. So, I did that. Guess what?! Fan stopped running at high speed and constantly! BACK TO NORMAL! Clearly, when re-connecting this monitor it has some BIOS or failsafe feature that kicks on the fan to run at high speed and non-stop, and turning off/on resets that feature back to normal operation. But thank you Best Buy Geek Squad for reminding me it's often the simple solution that ends up working to fix an issue.
